Schedule 40 Carbon Steel Pipe
Common Applications:
Schedule 40 carbon steel pipe is used in virtually every industry:
Plumbing and HVAC: Water supply and drain lines, heating systems, air conditioning condensate lines.
Industrial Process Piping: Transporting process water, air, steam, oil, and other fluids in factories and plants.
Oil and Gas: Gathering lines, production piping, utility lines (non-critical service).
Fire Protection Systems: Sprinkler system piping (often specifically required by code).
Structural Applications: Used as columns, handrails, frames, and support structures. In this case, the pressure rating is less important than the mechanical strength.
General Fabrication: For frames, rollers, and custom projects.
